Study on the Electromigration Organization and Mechanical Properties of Sn2.5Ag0.7Cu0.1RE/Cu Solder Joints
Published 2025-01-01“…The results showed that the angle θ between the c-axis of the β-Sn grain and the current direction for the Sn2.5Ag0.7Cu0.1RE/Cu solder joint gradually decreased to 8.2° when the temperature increased to 150 °C, which accelerated the diffusion of Cu atoms and Cu substrate dissolution. The recrystallization and grain growth of Cu<sub>6</sub>Sn<sub>5</sub> (An intermetallic compound formed by the fusion of copper and tin in a ratio of six to five) grains in the anode region promoted electromigration polarity. …”

Hydrothermal synthesis of a nickel-oxide-infused orange peel nanobiocomposite for enhanced heavy metal removal from mining wastewater
Published 2025-06-01“…The adsorption mechanism involves a two-step process where positively charged Cd2⁺ and Pb2⁺ ions diffuse toward the negatively charged surface of the Alg-OP-Ni nanobiocomposite and subsequently fix through interactions with surface oxygen atoms. Maximum adsorption capacities for Cd2⁺ and Pb2⁺ were determined to be 138.25 and 276.00 mg/g in single-component systems, and 224.00 and 317.10 mg/g in binary systems, respectively. …”

Picometre-level surface control of a closed-loop, adaptive X-ray mirror with integrated real-time interferometric feedback
Published 2025-01-01“…We demonstrate an unprecedented level of fast and precise optical control in the X-ray domain: the profile of a macroscopic X-ray mirror of over 0.5 m in length was freely adjusted and stabilized to atomic level height resolution. Aside from demonstrating the extreme sensitivity of the interferometer sensors, this study also highlights the voltage repeatability and stability of the programmable high-voltage power supply, the accuracy of the correction-calculation algorithms and the almost instantaneous response of the bimorph mirror to command voltage pulses. …”
